Step 1: Cook the manicotti shells according to package directions until al dente. Be careful not to overcook them, as they will bake further. Drain gently and rinse with cold water to prevent sticking. Lay them on a clean kitchen towel to dry slightly.
Step 2: While the pasta cooks, prepare the ricotta filling. In a large bowl, combine the ricotta cheese, beaten egg, 1/2 cup Parmesan cheese, 1 cup mozzarella cheese, chopped fresh parsley, salt, and black pepper. Mix until all ingredients are well combined and the mixture is smooth and creamy. This is the heart of your manicotti recipe.
Step 3: Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish with olive oil. Spread about 1 cup of marinara sauce evenly over the bottom of the prepared baking dish. This layer prevents the manicotti from sticking and adds flavor.
Step 4: Fill each manicotti shell with the ricotta mixture. You can use a spoon, but for easier and less messy filling, transfer the mixture to a piping bag (or a large Ziploc bag with a corner snipped off). Gently pipe the filling into each shell until full. This makes the manicotti recipe much more manageable.
Step 5: Arrange the filled manicotti shells in a single layer in the baking dish over the marinara sauce. Don't overcrowd them. If necessary, use two dishes.
Step 6: Pour the remaining marinara sauce evenly over the filled manicotti shells, ensuring they are well covered. This keeps them moist and flavorful during baking. This step is crucial for a juicy manicotti recipe.
Step 7: Sprinkle the remaining mozzarella cheese and extra Parmesan cheese generously over the top of the sauce. For a beautiful golden crust, ensure even coverage.
Step 8: Cover the baking dish tightly with aluminum foil. Bake for 30 minutes. Then, remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted, bubbly, and lightly golden brown. This ensures your manicotti recipe is cooked through and delicious.
Step 9: Once baked, remove the manicotti from the oven and let it rest for 5-10 minutes before serving. This allows the dish to set and makes it easier to serve. Garnish with extra fresh parsley or basil, if desired. Enjoy your homemade manicotti recipe!
